折线配筋先张预应力砼梁在公路桥梁中的应用探讨

Study of Application of Pre-tensioned Girder with Reinforcements in Broken Line to Highway Bridges

折线配筋先张预应力砼梁已成功应用于青藏铁路,而在公路桥梁中的应用几乎为零。提出了折线配筋应用于公路桥的一些设计方案,对折线配筋先张法的张拉工艺做了初步探讨。

In qingzang railway, pre-tensioned girder with reinforcements in broken line was successfully used, but has not been used in highway bridges. This paper put forward some method about the application of Pre-tensioned girder with reinforcements in broken line to highway bridge design, and studied the construction technique of pre-tensioned girder with reinforcements in broken line.
